High-throughput few-layered BN nanosheets have been synthesized through a facile chemical blowing route. They possess large lateral dimensions and high surface area, which are beneficial to fabricate effectively reinforced polymeric composites. The demonstrated composites made of polymethyl methacrylate and BN nanosheets revealed excellent thermal stability, 2.5-fold improved dielectric constan...
This paper describes an experiment that determined the position, and its associated uncertainty, of a proton at three different depths inside of a polymethyl-methacrylate (PMMA) absorber. These observed positions prove the fact that one can predict the most likely path (MLP) of a proton moving through a uniform medium, as long as the displacement and angle of that proton are known at the absorb...
An experimental method is presented for the rapid evaluation of structured solids with microelastic degrees of freedom associated with the microstructure. By contrast with earlier methods based on size effect studies, the present method makes use of a single specimen subjected to holographic interferometry. Results are presented for polymethyl methacrylate and for a dense polyurethane foam, whi...
